when in battle, what (if any) tactic(s) do you use?
When I attack usually go the simple route. Weaken the enemy with some missiles (arrows mostly), followed by a frontal attack by my heavy infantry (unless facing a phanlanx), try to flank and/or attack the rear with some cavalry, while keeping some infantry and cavalry in reserve if needed.
It isnt much different when I'm defending. I weaken the enemy with as much as possible (arrows, artillery etc) and then usually wait for the enemy come to me.
so, what's yours?
